OCTAL BIDIRECTIONAL TRANSCEIVER WITH TRI-STATE OUTPUTS
General Description
The F245 contains eight non-inverting bidirectional buffers with TRI-STATE outputs and is
intended for bus-oriented applications. Current sinking capability is 24 mA (20 mA Mil)
at the A ports and 64 mA (48 mA Mil) at the B ports. The Transmit/Receive (T/R) input
determines the direction of data flow through the bidirectional transceiver. Transmit
(active HIGH) enables data from A ports to B ports; Receive (active LOW) enables data from
B ports to A ports. The Output Enable input, when HIGH, disables both A and B ports by
placing them in a HIGH Z condition.

Note 2:
Absolute maximum ratings are those values beyond which the device may be damaged or
have its useful life impaired. Functional operation under these conditions is not
implied.
Either voltage limit or current limit is sufficient to protect inputs.
